.~.~ Having valve, director, or restrictor in pulse fluid flow path
DEFINITION
Classification: 60/591
(under subclass 533) Apparatus with distinct valve or restrictor structure in the flow path between the master and slave controlling the rate of flow of the pulse fluid or controlling flow between passages in the flow path to establish a rate of movement of the slave or to control or relieve pressure in the apparatus.
SEE OR SEARCH THIS CLASS, SUBCLASS:
569, for a pulsator having a valve in the flow line for maintaining the position of a slave by sealing pulse fluid in the slave.
590, for a device limiting the return flow of pulse fluid from a spring biased slave.

137, Fluid Handling,
455+, for a line condition responsive valve, per se; and subclass 561 for a fluid handling system of general utility.
188, Brakes,
297+, for an internal resistance motion retarder comprising a resistance means retarding flow between two chambers to dampen motion (e.g., shock absorber, dashpot, etc.).
303, Fluid-Pressure and Analogous Brake Systems, appropriate subclass for a valve, per se, or in combination with a nominal slave specialized for use in distributing fluid between branches in a brake system.
